SAW-SET.

Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed February 14, 1905. Serial No. 245,606.

10 all whom it may concern:

Be it known that I, J OHAN ENDRESEN, asubject of the King of Sweden andNorway, and a resident of Stavanger, Norway, have invented new anduseful Improvements in Saw-Sets, of which the following is aspecification.

My invention relates to improvements in saw-setting tools, moreparticularly of the plier type.

It has for its object, primarily, to effect the setting operation in asingle transit over the saw-blade, a plurality or two teeth beingreversely bent or set simultaneously step by step throughout theoperation to its completion, and to do this in an expeditious, simple,and effective manner.

Said invention consists ofcertain structural features, substantially ashereinafter more fully disclosed, and particularly pointed out by theclaims.

In the accompanying drawings, illustrating the preferred embodiment ofmy invention, Figure l is a side'elevation thereof. Fig. 2 is a planview of the same. Fig. 3 is an inverted view. Fig. 4 is a longitudinalsection, and Fig. 5 is a transverse section, produced on a line passingthrough the adjustable punch Fig. 6 is a detached perspective view ofsaid punch or depressor. Fig. 7 is a broken-away corresponding view ofthe jaw of the tool equipped with said punch or depressor, thelatter,however, beingremoved. Fig. Sis a detailed perspective view of thesaw-guide, an adjunctive part of said tool.

In the carrying out of my invention I provide two plier-like joined orarticulated together levers l 1, with the usual spring 2 held andinterposed therebetween to effect the automatic separation or throwingapart of the jaws 1 1 thereof after relaxing the grasp upon said levers.Upon laterally-extending portions of the articulating pivot or pintle 3of said levers are secured or fixed the lateral bars or arms 4 of thesaw-guide 4 of rectangular frame-like outline, with its forward endcross-bar extending beyond the forward end of and conforming to one ofthe lever-jaws, said lateral bars having secured thereto near theirinner ends a transverse rod or bar 4 passing intermediately of the jawsof said levers to properly position said guide thereon and hold it inthe requisite relation to the forward ends of said jaws. Said guide hasa slot 4" extending through its forward end crossbar and from side toside and penetrating the arms or lateral portions thereof to such extentas to receive and permit the placing therein of the saw within the planeof the action of the tooth deflecting or setting punches or depressorsof the tool.

The lever-jaws 1 1 are arranged to cooperate to effect thesaw-tooth-setting operation, one, 1, being preferably rectangular andhaving extending transversely therein near its extreme forward endpreferably a corresponding depression or recess l to receive, so as topermit endwise or lateral movement, an adjustable or sliding punch ordepressor 6, of peculiar construction, presently again referred to. Withthis recess or depression communicates an elongated slot 1, producedthrough the jaw 1 and passing through said slotis ascrew 5 fixed to andadjunctive of the punch or depressor 5, and upon said screw is fitted athumb-nut 5 for aiding the adjustment of the punch or depressor. Thepunch or depressor 5, of general rectangular outline, has upon its faceat one end a stepped offset 5", the broader surface of which, 5,provides a rest for a saw-tooth, while the narrow lateral ledge orextension 5" thereof forms a stop for said tooth, its right-lined edgeresting thereagainst, as in performing the setting operation. It will benoted that by moving or adjusting said punch either toward or.

away from the plane of action of the opposite lever-jaw saw-teeth ofvarying intervals apart may be acted upon or set, as desired.

The lever-jaw 1 is preferably of parrotbill-like contour in generaloutline, the same being equipped with a right-lined steel face or punch6, by the action of which as compression is exerted upon the two leversthe saw-tooth opposed thereto will be laterally bent or deflected in onedirection, while the offset surface 5 of the punch 5 willcorrespondingly deflect or bend the successive sawtooth in the oppositedirection through the reversely-exerted pressure therefrom, as will beapparent.

The amount of lateral deflection or set to be imparted to the saw-teethmay be varied or gaged by the suitable manipulation of a gage-screw 6,fitted to work in a screw-thread in one of the levers l 1 and engagingthe opposite or companion lever, a jam-nut 6 being applied to said screwand bearing upon the screw-equipped lever to fix said screw, thusproviding for limiting or controlling the relative movement of thelever-jaws equipped with the tooth-setting punches as required to effectthat purpose.

From the foregoing it will be noted that by means of my tool I amenabled to effect the setting of all the teeth of a saw at one operationor once going over the same, as will be appreciated, thus obviating thereverse passing of the tool over the saw, as where the teeth are setfrom opposite sides of the sawblade requiring the passing thereovertwice.

Latitude is allowed as to details herein as circumstances suggestwithout departing from the spirit of my invention.

I claim 1. A tool of the character described, comprising a setting blockor punch having a stepped member, with one edge thereof effectsitely tothe aforesaid lateral engagement of the first-referred-to tooth.

In testimony whereof I afiiX my signature in presence of two subscribingwitnesses.
